    So far I did not get anywhere with the card (tried monitor 1.3C and tried several boot addresses). Does it actually work in your system? If so I'd appreciate it if you could dump the eprom. I don't...

    Exidy Sorcerer Monitor 1.3C

    The Dutch company Gebr. van Montfort developed an improved monitor for the Exidy Sorcerer. Version 1.3 was sold in 1985. I scanned the (English) manual for it, made pictures of the envelope and the...

    It’s been a busy week so far, no retro time yet. I did find an envelope from 1985 with a monitor upgrade from the Gebr. van Montfoort, never installed. It is marked version 1.3C. According to the...

    Thanks for the links and suggestions, very helpful!

    Looking at the manual the card should have 2K ROM with firmware. My card only has one 1K PROM fitted so one 1K of ROM seems to be missing.

  6. California Computer Systems model 2422 FDC for Exidy Sorcerer

    With a recent purchase of an Exidy Sorcerer with an S-100 Expansion Unit came an S-100 FDC: the CCS 2422. Regrettably it does not work in the current configuration, I believe it may need (Sorcerer...

    The CP/M 2.2 is distributed by Compudata. I don't see any references to Compudata on the disk drives.

    The operation manual mentions that the capacity of a formatted disk for the 40T drive is 160K...

    Yes, the blue cable is for the second drive.

    The floppy disk subsystem add-on is nothing more than a second drive in the same enclosure as the DP6400. No PSU, no controller card. It takes power...

    If you are lucky the drive is fitted with a “floppy disk subsystem add-on”. It would have a cable to connect a second unit:

    You should then be able to connect a 80T 96TPI drive as a...

    A few months ago I managed to get a (dual) DP-6400, including working CP/M disks (also 2.2). So that is 40 tracks, not 77 tracks.

    The 77 tracks disks are 100 TPI, more modern drives are 96 TPI. It...

    Perhaps I’m missing something but keeping things simple could you not save the monitor rom to tape (or directly to a PC to convert to WAV)?

    You could also do that as a makeshift move tool: save...

    No, what I mean is that I can't get it to run again if I reload it, no matter what baud rate I save / load it. It simply crashes. It probably needs CP/M to function.

    With my CPM 2.2 I managed to...
